  • Video games have become a powerful tool to tell a complex story realistically thanks to modern technology. Rockstar Games' Red Dead Redemption 2 (2018), is a video game title that touts cinematic qualities such as superb acting by the voice actors and jaw-dropping cinematography as well as a rich narrative following the protagonist, Arthur Morgan's quest for redemption. Using Aristotle's Poetics and Robert Mckee's Aristotelian theory on storytelling, this study highlights Arthur's gradual change from a ruthless gunman to an altruistic hero, from which it derives the theme of redemption, and his super-objective to protect those he cares about. Then, it also explains a variety of possibilities in the narrative of the game determined by the opened-ended game mechanics, particularly the "honor" system, which reflects Arthur's moral choices on the narrative presentation with different sets of dialogue and endings. However, the study ultimately argues Red Dead Redemption 2 to be incohesive in its storytelling due to "ludonarrative dissonance," a concept coined by Clint Hocking, which indicates a conflict between the narrative and game mechanics of a video game. It's mainly because the game's various narrative choices bring changes to neither the theme nor Arthur's super-objective. Furthermore, the double-standard of evaluation in the "honor" system, and its numeric ranking system of honor also lend themselves to ludonarrative dissonance even further. After all, the study ultimately claims ludonarrative dissonance in Red Dead Redemption essentially disrupts the game's narrative unity, which is Aristotle's one of most emphasized upon traits of any story and signifies the game's instability as a storytelling medium.

  • Recently, interests and utilization on Computed Radiography(CR) and Digital Radiography(DR) tends to increase owing to an introduction of Picture Archiving and Communication System(PACS) and an accuracy control of special medical equipment for a breast imaging examination. This study was intended to compare and analyze a detector's imaging quality by each system to be used for the breast imaging examination by using ACR Phantom used at the accuracy control. As an evaluation method, a significance and reliability of image's value using the ACR Phantom was analyzed by using SPSS program. The results are followed. 1. For the fiber, there was 3.9 score in Screen-Film, 4.2 score in CR($50{\mu}m$), 3.2 score in CR($100{\mu}m$), and 4.2 score in DR. There was the high score in the order of CR($50{\mu}m$), DR, Screen-Film, and CR($100{\mu}m$)(P<0.05). 2. For the calcification, there was 2.7 score in Screen-Film, 2.5 score in CR($50{\mu}m$), 2.0 score in CR($100{\mu}m$), and 2.9 score in DR. There was the high score in the order of DR, Screen-Film, CR($50{\mu}m$), and CR($100{\mu}m$).(0.025(P<0.05). 3. For Mass, there was 3.8 score in Screen-Film, 3.8 score in CR($50{\mu}m$), 3.6 score in CR($100{\mu}m$), and 4.5 score in DR. There was the high score in the order of DR, CR($50{\mu}m$), Screen-Film, and CR($100{\mu}m$) (P<0.1). 4. As the total score, there was 10.4 score in Screen-Film, 10.6 score in CR($50{\mu}m$), 8.7 score in CR($100{\mu}m$), and 11.3 score in DR. There was the high score in the order of DR, $CR(50{\mu}m$), Screen-Film, and $CR(100{\mu}m$). As shown in the above results, it can be known that DR and Screen-Film System has higher image quality than CR. But, DR has unstability caused by element, and Screen-Film has the low image quality caused by artifact as disadvantages. When Dual-Side CR($50{\mu}m$) was used among CR systems which had the problem of low image quality, it was indicated that there was no difference with Screen-Film System. Because the radiation imaging examination tends to become digitalized, each system for the breast imaging examination will need to be developed and supplemented.
